Extracts of K. mortagei and K. fedtschenkoi used in this study.

Extract number	Species extracted	Plant part extracted	Extraction solvent	Yield (%)	Total phenolic content (mg GAE/g)
1420	K. mortagei	Leaves, stems (aerial parts), immature inflorescences	80% EtOH	19.62	331 ± 33
1468	K. mortagei	Leaves, stems (aerial parts)	95% EtOH	6.98	571 ± 87
1508	K. mortagei	Mature inflorescence, flowers	95% EtOH	16.13	818 ± 19
1509aq	K. mortagei	Mature inflorescence, flowers	H2O	22.25	1340 ± 116
1421	K. fedtschenkoi	Aerial parts (including woody stems)	80% EtOH	12.69	370 ± 17
1465	K. fedtschenkoi	Woody stems	95% EtOH	7.44	498 ± 50
1469	K. fedtschenkoi	Aerial parts (no woody stems)	95% EtOH	15.54	486 ± 6

Comparing the fresh biomass of each plant to its dry mass showed that the non-water portion comprised 7.90 and 5.78% of the overall mass for K. mortagei and K. fedtschenkoi, respectively. The TPC is expressed in mg GAE/g dry extract.
